The Sun released two M flares and seven high C flares during the past 24 hours. Most flares were produced by NOAA AR 2242 and 2241. An M6.9 flare was released by AR 2241 and peaked at 21:58 UT on December 18. An associated Type II radio burst was observed by the Palehua station on Hawaii, with an estimated shock speed of 664 km/s. LASCO C3 shows images of a probably associated halo CME after a data gap, first observed at 00:27 UT on December 19. Based on the estimated Type II shock speed, it is estimated that this CME will arrive at Earth around 0h UT on December 22. The second M flare was an M1.3 flare released by AR 2237 around 9:44 UT on December 19. There is a chance for proton storms in the days ahead. During the past 24 hours, solar wind speeds observed by ACE were nominal between about 330 and 430 km/s. The magnitude of the Interplanetary Magnetic Field (IMF) fluctuated between about 6 to 8 nT. During the past 24 hours, geomagnetic conditions were quiet (K Dourbes between 0 and 3; NOAA Kp between 1 and 3). Quiet geomagnetic levels (K Dourbes < 4) are expected on December 19. Active (K Dourbes = 4) to minor storm conditions (K Dourbes = 5) are possible on December 20 and 21 in view of the expected arrival of the halo CME from December 17.
